WILLIAM C. BAKER, OF NEW YORK, N. Y., ASSIGNOR TO THE BAKER HEATER COMPANY, OF SAME PLACE.

' RAI LWAY-CAR H EATER."`

SPECIFICATION forming part of Letters Patent No. 439,287, dated October 28, 1890.

Application filed January 24, 1888. Serial No. 261,7 85. (No modeL) v vTo all whom it' may concern:

Beit known that l, WILLIAM C. BAKER, of the clty, county, and State of New York, have invented an Improvement in Railway-Car Heaters, of which the following is a speciiication. Railway-car heaters have been extensively introduced 1n which water is made' to circulate through radiating-pipes in the car, which Y as shown in my patent, No. 331,367, granted December 1, 1885; butin all instances it has been necessary to make use of a shovel to supply the coal i'ntcthe fire-chamber. In doing this the dust is liable to pass out into the car, and sometimes gases escape at the fuel- My present improvement is for rendering the heater and fuel-supply morecompact and for passing the fuel into the tire-chamber without the use of a shovel, and this can be done while the heater is in a closed condition, and I also provide for introducing fuel in the ordinary manner, so that the fire can be fed in case the elevated coal-bin becomes eX- hansted.

In the drawings, Figure 1 is an elevation of my improved heater with the elevated coalbin, and Fig. 2 is a vertical sect-ion of the same. Fig. 3 is a plan below the line a: 0c, and Fig. 4 is a partial vertical section at the line y y, Fig. 3.

The water-heatin g coil A is within the firechamber B, and this is provided with a grate C above the ash-pit D, and the whole is inclosed in a case E, having a door F to the ash-pit, as represented in my application, Serial No. 256,491,f`1led November 30, 1887, and at the top of the fire-chamber is a supplypipe G and safety-plate, and this safety-plate is pivoted and can be swung up within vthe casing K. I have represented these parts as best adapted to my present elevated coal-bin; but I do not limit myself in the use of said elevated coal-bin to the details of the con in the base of the elevated coal-bin, and the same is preferably pivoted at one side, so that it can be turned up by a key or wrench S, introduced through a hole in the side of the casing, but preferably through the doorway when the` door W is slid aside and setting upon a square at the hinge or pivot of the valve, and the valve rests at its edges upon the shoulder or offset at the discharge-opening Q. Hence the weight of the.k coal closes the valve, and it is opened by sufficient force to slightly lift the coal, and it is preferable to notch this door W at one side so as to close the same upon the shank of the key or wrench to keep the dust from passing out into the car. Outside the coal-bin L is a casing T, attached at its lower end to the top portion of the safety-casing around the re-chamber, and' there isa space between the elevated coal-bin L and the case T, which forms a flue for the escaping products of combustion from the tire-chamber, and at the top of the case T is a conical contraction U, that unites the case T and the smoke-flue V, and through this conical contraction U the supply chute M passes..

It will be apparent that the products of combustion as they pass up around the elevated coal-bin warm up the coal; but the heat is not sufcient to ignite the same, and these products of combustion escape by the flue V through the roof of the car, as usual, and the supply-chute M may also pass through the roof or the side of the car, wherever lnostconvenient for receiving the supply of coal.

The door W isjitted to slide in top and bottom guides around the outside of the casing T, and it covers the opening through the casing T, and there is also an opening at this point through the lower portion of the elevated coal-bin support K, so that access is IOO given to the safety-plate H. Hence when coal 1s to be supplied to the fire the door NV is turned aside and the safety-plate H unlatched, raised up,and thrown back, so as to open the space for the coal to pass down into the firechamber upon turning or moving the valve R, preferably after the door NV has been closed, as aforesaid; and this safety-plate is closed (immediately after the supply of coal has been shut off) in the usual manner with the heaters heretofore constructed by me and before the door W is shut, and this door W gives opportunity for introducing fuel by a shovel should the supply of coal in the elevated coal-bin be exhausted.

The safety-plate H is of a size to lill the upper end of the supply-pipe G, and it is pivoted at opposite sides, as seen in Fig. 2, so that it may be swung up into the position shown in Fig. 4, and there is a spring-latch (see Fig. et) to hold the safetyplate when closed down.

I find it convenient to make a long vertical opening through the case T and through the elevated coal-bin, as shown at X, and to introduce a frame at this point that joins the easing and coal-bin, and into this frame a plate of thick glass is introduced, and one or more vertical bars at the back of the glass prevent the coal coming into direct contact with such glass, but permit the attendant to see Whether there is a sufficient supply of coal in the coal-bin. It is preferable to provide two of these frames and glasses at opposite sides of the elevated coal-bin in such positions that light is admitted at the back of the coalbin, so that the height of the coal may be more easily inspected, even When the glasses may have become coated more or less With coal dust or soot; and it is preferable toA introduce a mica Window in the door W, as at 10, so as to be able to observe the quantity of coal admitted to fall into the fire-chamber.

I claim as my inventionl. The railway-car heater having a firechamber and a supply-tube G above the same, in combination with the safety-plate H for closing the supply-tube, an elevated coal-bin and the support K for the same around the supply-tube, a ease T around the elevated Goal-bin, forming a flue between the same and the coal-bin for the products of combustion, theeontracted top U to the said case, and a smoke-flue V and supply-chute for the coalbin at the upper part thereof, substantially as set forth. Y

2. The elevated coal-bin having a hoppershaped bottom and opening, in combination with a railway-car heaterhaving a fire-chamber and a supply-tube G and safety-plate H, the support K for the coal-bin around the supply-tube and safety-plate, the casing T, with an opening therein, and the door Wfor giving access to the safety-plate and to the top of the tire-chamber, substantially as set forth.

3. The combination, with the railway-car heater having a fire-chamber and an inclosing-case, of an elevated coal-bin having an opening at the lower portion thereof above the supply-opening to the fire-chamber, -a valve to shut off the supply of fuel, a safetyplate to the su pply-opening of the fire-cham ber, a case around the elevated coal-bin having an opening near the safety plate and valve, and a door to the' saine, substantially as set forth.

Signed by lne this 23d day of January, 1888.

W. C. BAKER.
